Overview
{{{
for i in words; do commands; done
}}}
If the keyword "in" is not present, Template:For will iterate through positional parameters.
Alternative form:
{{{
for (( i=0; i<${#names[@]}; i++ )); do local name=${names[${i}]} echo "${name}" done
}}}
!!!Iterating through $1, $2, $3 ...
{{{
for i do echo ${i} done
}}}
!!!Iterating through a space separated list
{{{
s="a b c"
for i in ${s} do echo ${i} done
}}}
or
{{{
s="a b c"
for i in ${s}; do echo ${i}; done
}}}
Note the use of ";"
